Network equipment throughput limiting method, network equipment throughput statistical method, network equipment throughput limiting device, and network equipment throughput statistical device

Abstract

The invention provides a network equipment throughput limiting method, a network equipment throughput statistical method, a network equipment throughput limiting device, and a network equipment throughput statistical device. The network equipment throughput limiting method comprises the following steps: counting a timeout period of a virtual system of the network equipment from a throughput limitof the previous virtual system; if the timeout period does not exceed the limit time interval and when the statistical value of the throughput limit of the current virtual system is greater than or equal to the throughput limit value of the virtual systems, performing packet loss processing; if the timeout period exceeds the limit time interval, updating the timeout period of the throughput limitof the virtual systems as a current time, and using atomic operations to reset the statistical value of the throughput limit of the virtual systems. The specification scheme achieves precise control through the throughput limit by atomic operations, and reduces the impact on the performance of network equipment. In addition, the implementation scheme of throughput real-time monitoring statistics and throughput limitation separation is used to greatly reduce the impact of throughput limiting functions on equipment performance.

Description

technical field [0001] This specification relates to the field of computer Internet technology, and in particular to a method and device for limiting the throughput of network equipment, and a method and device for counting the throughput of network equipment. Background technique [0002] In actual network application scenarios, for network devices that support virtual systems, in order to monitor the real-time application of network devices, it is necessary to monitor the throughput of each virtual system in real time. To effectively supervise the usage, sometimes it is necessary to limit the throughput of some virtual systems, and even carry out different restrictions according to the different conditions of the application users of each virtual system. The throughput of the system requires that the throughput of each virtual system be limited according to user configuration requirements. [0003] A virtual system (Virtual System) refers to logically dividing a physical ...

Problems solved by technology

[0005] The above-mentioned existing technical solution, when the CPU multi-core processing mechanism processes the business, the business processing will be distributed to each business processing data core as evenly as possible, but because the throughput of each traffic packet in the actual network application is not fixed and cannot be randomized Controlled, the absolute business average of each CPU data core cannot be achieved, resulting in the throughput of some CPU data cores exceeding the limit value, while some CPUs have not exceeded the throughput limit value, which affects the accuracy of the throughput limit

In addition, with the rapid development of technology, there are differences in the usage of each CPU data core among different types of network devices. If the throughput limit is completely dependent on the usage of each CPU data core and service allocation, the limitations will become more prominent and cannot Compatible with network devices of different product types and CPU types
